2013-04-08hw: move target-independent files to subdirectoriesPaolo Bonzini1-2136/+0
This patch tackles all files that are compiled once, moving them to subdirectories of hw/. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-04-08hw: move headers to include/Paolo Bonzini1-1/+1
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-03-01hw: include hw header files with full pathsPaolo Bonzini1-3/+3
Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

2013-01-10Make all static TypeInfos constAndreas Färber1-1/+1
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity1-6/+6
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-07-26lsi: avoid redundant tests of s->current != NULLPaolo Bonzini1-2/+3
Simplify the code by checking against req->hba_private directly, and asserting that it is non-NULL before a command is completed or canceled. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-07-26lsi: use qdev_reset_allPaolo Bonzini1-12/+3
By first resetting the devices, lsi_soft_reset will find the queue already cleared so there is no need to do that forcibly (which may also leak SCSIRequests, and/or worse due to dangling references to the lsi_request in the hba_private field). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-06-18qbus: Make child devices linksAnthony Liguori1-2/+3

2012-02-22scsi: pass residual amount to command_completePaolo Bonzini1-1/+1
With the upcoming sglist support, HBAs will not see any transfer_data call and will not have a way to detect short transfers. So pass the residual amount of data upon command completion. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-02-15qom: Unify type registrationAndreas Färber1-2/+2
Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

2012-02-03qdev: remove baked in notion of aliases (v2)Anthony Liguori1-2/+0
Limit them to the device_add functionality. Device aliases were a hack based on the fact that virtio was modeled the wrong way. The mechanism for aliasing is very limited in that only one alias can exist for any device. We have to support it for the purposes of compatibility but we only need to support it in device_add so restrict it to that piece of code.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori1-8/+11
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-01-27qdev: move qdev->info to classAnthony Liguori1-1/+1
Right now, DeviceInfo acts as the class for qdev. In order to switch to a proper ObjectClass derivative, we need to ween all of the callers off of interacting directly with the info pointer. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-10-28scsi: add channel to addressingPaolo Bonzini1-2/+2

2011-10-28scsi: allow arbitrary LUNsPaolo Bonzini1-1/+2
This only requires changes in two places: in SCSIBus, we need to look for a free LUN if somebody creates a device with a pre-existing scsi-id but the default LUN (-1, meaning "search for a free spot"); in vSCSI, we need to actually parse the LUN according to the SCSI spec. For vSCSI, max_target/max_lun are set according to the logical unit addressing format in SAM. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-10-28scsi: remove devs array from SCSIBusPaolo Bonzini1-15/+7
Change the devs array into a linked list, and add a scsi_device_find function to navigate the children list instead. This lets the SCSI bus use more complex addressing, and HBAs can talk to the correct device when there are multiple LUNs per target. scsi_device_find may return another LUN on the same target if none is found that matches exactly.

2011-08-12scsi: pass cdb already to scsi_req_newPaolo Bonzini1-2/+2
Right now the CDB is not passed to the SCSIBus until scsi_req_enqueue. Passing it to scsi_req_new will let scsi_req_new dispatch common requests through different reqops. Moving the memcpy to scsi_req_new is a hack that will go away as soon as scsi_req_new will also take care of the parsing.

2011-07-19scsi: Add 'hba_private' to SCSIRequestHannes Reinecke1-14/+8
'tag' is just an abstraction to identify the command from the driver. So we should make that explicit by replacing 'tag' with a driver-defined pointer 'hba_private'.
